	<abstract content_type="html">From January to March 2005, the Atmospheric Chemistry Experiment high
resolution Fourier transform spectrometer (ACE-FTS) on SCISAT-1 measured
many of the changes occurring in the Arctic (50&amp;ndash;80&amp;deg; N) lower stratosphere
under very cold winter conditions. Here we focus on the partitioning between
the inorganic chlorine reservoirs HCl and ClONO&lt;sub&gt;2&lt;/sub&gt; and their activation
into ClO. The simultaneous measurement of these species by the ACE-FTS
provides the data needed to follow chlorine activation during the Arctic
winter and the recovery of the Cl-reservoir species ClONO&lt;sub&gt;2&lt;/sub&gt; and HCl. The
time evolution of HCl, ClONO&lt;sub&gt;2&lt;/sub&gt; and ClO as well as the partitioning
between the two reservoir molecules agrees well with previous observations
and with our current understanding of chlorine activation during Arctic
winter. The results of a chemical box model are also compared with the
ACE-FTS measurements and are generally consistent with the measurements.</abstract>
